Bugs send me here to ask re. the reporting of this. Please enlighten me where this should belong.
It started after upgrading to Opensuse Leap16.0 and the new version of KDE. When I start Dolphin or Krusader in user mode, no problem. Do I start them in Super mode, after the password there is no window, although System monitor shows them running. The only way to get them showing up in Super mode is first call Terminal as Super and from there call a file manager.
When Krusader is running in Super, File Manager Super Dolphin starts up and immediately shuts down. Obnoxious competitive intolerance?
One comment: It seems that KDE now gets the Microsoft Renewance bug. Things that are clear and function well because of their simplicity are replaced by something new, because new form goes before function. In the task bar there were quite clear status widgets of a loudspeaker, a clipboard, a battery and a USB stick; now they are replaced by befuddling icons that on a laptop screen are hardly different from a grey blob. The old icons were easily distinguishable, even in small screens. Bring them back in setup and let the user decide which to use.
You did not quote the essence of the comment about the widget icons in the task bar. They are there, of course, but what is not in the quote is that the unnecessary optical renewal has made them just grey blobs. Get a 14” laptop at the highest resolution and you will see what I mean. They were simple and consequently clear, so any fancification could and indeed did only go the wrong way. E.g., compare the old USB icon (disks & devices) in the overflow (when no stick is inserted) with what pops up in the bar when you actually insert a stick.
I am not deprecating your intention and effort, though.
